Compatibility & preservation notes
E-ATX up to 12 × 13 in, ATX and microATX; seven full-height expansion slots. Board and PSU clearances are manual-specific.
Preserve trays, key, acoustic panels, fan ducts and rails. Label bay order/controller mapping; heavy carriers and rack rails require careful handling.
- Record the complete model/SKU, serial/date label, board and bay/backplane identifiers, accessories and manual revision before disassembly.
- For servers/workstations, match the exact riser, backplane/controller, drive carrier, PSU and rail kit; a matching 2U/4U height alone does not ensure compatibility.
- Keep original brackets, fasteners, trays, feet and front-panel parts labeled with the chassis. Do not force components into modified or incomplete specimens.
